.A rectangular field is 112 m long and 100 m wide. Two roads, each 3 m wide are to be
constructed at the centre of this field, one
is parallel to the length of the field and the
other is parallel to the breadth of the field.
a) area of the two roads.
b) area of the part of the field, not covered
c) cost of constructing the roads at 17 per m.

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

overcharge is the right answer system

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
